AC Black Flag Resynced Stealth Guide : How to Never Get Detected
Most missions let you ghost through without a fight. Here is how to use Eagle Vision, whistling, hiding spots, and the environment to never raise an alarm.
- •Eagle Vision marks enemies through walls. Use it constantly. Tag enemies with RT to track them permanently.
- •Whistle from cover to lure one guard at a time. Clear patrols by pulling them toward you.
- •Rooftops are always safer than streets. Guards rarely look up. Use the high ground.

Eagle Vision is not optional
Press it. Use it constantly. It marks enemies in red, objectives in green, and interactables in yellow. Hold RT on an enemy to tag them permanently through walls. If you are not using Eagle Vision, you are playing on hard mode.
Whistle from cover
Bushes. Haystacks. Behind walls. Whistle. One guard will investigate. Kill them silently. Whistle again. Repeat. This clears entire patrols without raising alarms.
Rooftops are your friend
Guards patrol streets. They rarely look up. Use rooftops to bypass most enemies. The parkour system is designed for this. Stay high. Stay unseen.
Hide bodies
Guards who find dead bodies raise alarms. If you kill someone in the open, move the body into a bush or haystack. Or just do not kill anyone you do not need to.
